A disk player has a disk cartridge for being loaded thereon, and accommodating a disk-type recording medium. The disk cartridge has a shutter arranged thereon, for performing slide-opening/closing in order to expose an information surface of the disk-type recording medium. The disk player includes a carrier mechanism for carrying the disk cartridge to an information regenerating location and an information recording location, and a shutter sliding mechanism for slide-opening/closing the shutter. The shutter assumes an intermediate position of sliding when the disk cartridge is located at one of the information regenerating location and. the information recording location, and assumes a terminal position of sliding when the shutter is located at the other one of the locations. The disk player also includes a driving mechanism including an engaging element and an engaged element which is separated from the engaging element when the information recording mechanism is not driven.

Disk player

A disk player has a structure capable of mounting on a turntable a disc-shaped recording medium contained within a cartridge. Such disc player comprises a cartridge transporting system capable of transporting the cartridge in a direction generally parallel to a sliding direction of a shutter of the cartridge; and a pivotable chassis on which the turntable is mounted, said chassis being pivotable by a chassis driving system so as to enable said disc-shaped recording medium to be mounted on the turntable, with its pivoting axis being generally parallel to a transporting direction for transporting the cartridge.

Disc player having an improved disc cartridge loading system

A disk player comprises a turntable for rotatably holding an optical disc; an optical pickup for recording information into and reading information from the optical disc, an elongated guide shaft arranged in a predetermined moving direction of the optical pickup for guiding the optical pickup to move in said predetermined direction, a pivotable chassis for mounting the turntable, the optical pickup and the elongated guide shaft, a cartridge holder for receiving and holding a cartridge containing the optical disc. In particular, an adjustment mechanism is provided on the pivotable chassis for adjusting a positional relationship between the optical pickup and the turntable by moving one end of t he elongated guide shaft in a plane which is generally parallel with a recording surface of the optical disc.
